The subject matter described herein discloses apparatus, systems, techniques and articles for automatically tracking engine component life cycle data. The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. As used herein, the word “exemplary” means “serving as an example, instance, or illustration.” Thus, any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. All embodiments described herein are exemplary embodiments provided to enable persons skilled in the art to make or use the invention and not to limit the scope of the invention which is defined by the claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, summary, or the following detailed description.

FIG. 1 is a block diagram depicting example components on an example aircraft. The example aircraft includes an engine mounted communication module 102, an aircraft mounted engine electronic controller 104, and a plurality of engine components comprising a plurality of line replaceable units (LRUs) 106, 108, 110, 114, 122, 124, 126 and other engine components 112, 116, 118, 120. The LRUs 106, 108, 110, 114, 122, 124, 126 and the other engine components 112, 116, 118, 120 are each equipped with radio frequency identification (RFID) tags mounted on or proximate thereto that can transmit, receive, and store data. The engine mounted communication module 102 can communicate with each of the RFID tags to retrieve data transmissions from the RFID tags and to transmit data to the RFID tags for storage.

The engine mounted communication module 102 also communicates with an aircraft mounted engine electronic controller 104 and acts as an intermediary between the electronic controller 104 and the RFID tags. The communication module 102 receives data in the form of RF transmissions from the RFID tags and relays the data to the electronic controller 104. The communication module 102 also receives information from the electronic controller 104 and transmits the information to the RFID tags. In this example, the engine mounted communication module 102 can further communicate wirelessly via cellular transmissions, satellite transmissions, and/or other wireless transmissions to one or more external systems 128 (such as an aircraft maintenance system or engine maintenance system) to download data to the external system 128. In other examples, the engine mounted communication module 102 may not communicate wirelessly.

The engine mounted communication module 102 therefore may include an RF transceiver to facilitate information exchange between the RFID tags and the communication module 102. The engine mounted communication module 102 may also include a cellular transceiver, satellite transceiver, and/or other wireless transceiver to facilitate an information exchange between an external system 128 and the communication module 102.

The LRUs in the example aircraft 100 include an IGV actuator 106, a fuel module 108, a surge control valve 110, a bleed valve 114, a lube module 122, starter/generator system 124 and an exciter 126. The other engine components in the example aircraft 100 include fuel nozzles 112, an inlet scroll 116, turbines and compressor wheels 118, and an engine gearbox mounted nameplate 120. Each of the LRUs and other components in this example includes an associated RFID tag that is mounted on or near the engine component.

The RFID tags are configured to receive data for storage, store received data, and to transmit stored data. In this example, each RFID tag stores static, repair, and dynamic data regarding the LRU or other engine component with which the RFID tag is associated. The static data includes identification information regarding the associated engine component, the repair data including repair history information regarding the associated engine component that is recorded by the RFID tag, for example, during visits by the engine component to a repair shop, and the dynamic data includes engine usage information, component usage information, and component fault information regarding the associated engine component.

The engine usage information may include operating hours and operating cycles experienced by the engine. The component usage information may include operating hours and operating cycles experienced by the engine component. The component fault information may include fault codes and fault messages.

The dynamic data may include environmental measurements such as temperature, vibration, ice accumulation, and others. The dynamic data for one engine component may be different from the dynamic data for another engine component. As an example, the dynamic data for the IGV actuator 106, fuel module 108, and fuel nozzles 112 may each include temperature, vibration, operating hours and operating cycles. The dynamic data for the surge control valve 110 and the exciter 126 may each include total operating hours and operating cycles.

The engine electronic control module 104 may be configured to retrieve, using the communication module, static data and repair data from each RFID tag, store the static data and the repair data for each engine component in a database in storage media accessible by the controller, and store dynamic data in the database for each engine component, for example, after each engine cycle. The engine electronic control module 104 may also be configured to transmit, using the communication module, dynamic data regarding an engine component to each engine component's associated RFID tag, for example, after each engine cycle for storage in the RFID tag. The engine electronic control module 104 in this example is further configured to perform operations to transmit, using the communication module, the static data, the repair data, and the dynamic data to the external system 128.

In this document, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Numerical ordinals such as “first,” “second,” “third,” etc. simply denote different singles of a plurality and do not imply any order or sequence unless specifically defined by the claim language. The sequence of the text in any of the claims does not imply that process steps must be performed in a temporal or logical order according to such sequence unless it is specifically defined by the language of the claim. The process steps may be interchanged in any order without departing from the scope of the invention if such an interchange does not contradict the claim language and is not logically nonsensical.

Furthermore, depending on the context, words such as “connect” or “coupled to” used in describing a relationship between different elements do not imply that a direct physical connection must be made between these elements. For example, two elements may be connected to each other physically, electronically, logically, or in any other manner, through one or more additional elements.
